How to get links in each block PHP DomReady?

I have the following HTML DOM:

<div class="m">
<div class="cr"><a class="link" href="1">1</a><div class="title">1</div></div>
<div class="cr"><a class="link" href="2">2</a><div class="title">2</div></div>
<div class="cr"><a class="link" href="3">3</a><div class="title">3</div></div>
</div>

I need to get in one loop values: .title and href of links.

I tried:

$similar = $xpath->query('//div[@class = "cr"]');

foreach ($similar as $key => $item) {
    $href = ?
    $title = ?
}

You could use the SimpleXMLElement Class for that as demonstrated by the Snippet below which, you may Quick-Test Here.

<?php

    $html = '<div class="m">
            <div class="cr"><a href="1">1</a><div class="title">1st Node Value</div></div>
            <div class="cr"><a href="2">2</a><div class="title">2nd Node Value</div></div>
            <div class="cr"><a href="3">3</a><div class="title">3rd Node Value</div></div>
            </div>';


    $sXML       = new SimpleXMLElement($html);
    $links      = $sXML->xpath("child::div/a");
    $titles     = $sXML->xpath("child::div/div");

    $arrLinks   = array();
    $arrTitles  = array();

    foreach($links as $link){
        $arrLinks[]     = (string)$link->xpath("attribute::href")[0];
    }

    foreach($titles as $title){
        $arrTitles[]    = (string)$title;
    }

    var_dump($arrLinks);        
    // YIELDS::
    array (size=3)
      0 => string '1' (length=1)
      1 => string '2' (length=1)
      2 => string '3' (length=1)

    var_dump($arrTitles);
    // YIELDS::
    array (size=3)
      0 => string '1st Node Value' (length=14)
      1 => string '2nd Node Value' (length=14)
      2 => string '3rd Node Value' (length=14)
